Value of some types of links (.js & .php)?

[tomellis]

I have been actively building links for my site for several years with pretty good results. Recently as I have been checking up on my link partners I have found that an increasing number are now using links that are either located on pages that are accessed through javascript links, or are on .php addressed pages rather then .htm or .html.

Am I correct that the robots can't follow a javascript link, in which case the links on these pages are worthless? And I am not at all clear on exactly how .php works, and whether links on these pages are also of lesser value than those on .htm or .html pages.

I am anxious to hear from the community your thoughts on this. If I have a bunch of "link partners" whose links to my site are effectively invisible, I want to remove those links from my site ASAP.

Thanks!

With PHP links don't worry. There is no difference between let's say index.htm and index.php when it comes to crawling. I am no PHP programmer, but I'm positive that php generated web pages are easily crawled by SE spiders. Unless the page is accessible via a login procedure or it has complicated password protected calls to database for content, don't worry about accessibility.

I don't know about Java Script links.
